  • Patent number: 7584531
    Abstract: A method of manufacturing a golf club head with a variable thickness face having a central thickened region surrounded by a transition region tapering from the central thickened region to a thinner peripheral region. The method includes locating a ball end mill revolving about an axis generally normal to the inner surface of the face plate at an initial location on a circumferential intersection between the outer edge of the central thickened region and a transition region. The inner surface of the face plate is machined by moving the revolving ball end mill in a radial direction outwardly toward and through the transition region and the peripheral region to machine the inner surface of the face plate creating a tool channel having a width as the ball end mill traverses the transition region and thereby vary the thickness of the face plate in the tool path.
